Answer:
Option-C (The two carbon atoms share a total of six electrons with each other) is the correct answer.
Explanation:
According to statement the compound explained is Acetylene. It is an unsaturated hydrocarbon and belongs to class of Alkynes containing Carbon-Carbon triple bonds.
The lewis structure of Acetylene is attached below. As a single covalent bond is formed by sharing of two electrons therefore, the three bonds (triple bond) between the two carbons atoms will contain six electrons in total.
First option is incorrect because there is no lone pair of electrons on either Carbon or hydrogen atoms.
Second option is incorrect because the octet of both carbon atoms is complete.
Fourth option is incorrect because the electronegativity difference between carbon and hydrogen atoms is 0.4 and hence, the bond is nonpolar in nature.
